Extended Data Fig. 7: Total acid-leachable lead (TPb) concentrations (pmol L−1) along the shelf-deep basin gradient.
From: Arctic Ocean’s wintertime mercury concentrations limited by seasonal loss on the shelf
Stations P1–P7, (Latitude) are on the x-axis for summer 2019 (top) and winter 2019 cruises (bottom). Data points at or below the detection limit were assigned the value of the detection limit (1.08 pmol L−1) determined by the seaFAST-pico ICP-MS for plotting purposes. Black contour lines for THg (pmol L−1) from each corresponding season are overlain. Concentrations greater than the presented range (25 pmol L−1) are plotted as the maximum. Figure created using Ocean Data View51.
